Improvement in water-elevators



UNITED STATES PATENT OFFICE..

GEORGE RAGE, OF NORWIOH, NEW YORK.

IM PROVEMENT IN WATER-ELEVATO RS.

Specification forming part of Letters Patent No. 35,891, dated July l5, 18652.

To all whom it may concern:

Be it known that I, GEORGE RACE, of Norwich, Ohenango county, New York, have invented a new and useful Improvement in Vindlasses for the Purpose of Elevating YVater; and I do hereby declarethat the following is a full and exact description thereof, reference being had to the accompanying drawings, which form a part of this specification.

Similar letters indicate the same portions of my invention in cach iigure shown in the said drawings.

The object of this invention is to obtain a means of elevating water which can be operated with greater facility than any method known to your petitioner.

The invention relates to that class of waterelevators in which a windlass and bucket are employed; and it consists in the employment or use of a ratchet placed loosely on the windlass-shaft, in connection with a wheel permanently attached -to the windlass-shaft and inclosed within a barrel attached to the ratchet, said wheel being acted upon bya friction band or clutch', which band is so arranged as to beA operated at pleasure by means of a ratchetlever, to which the handle is attached by means of the cogged wheel or pinion permanently attached to the said handle, as herein.

after described, whereby the bucket may be elevated by rotating the crank and released at any time or suddenly stopped, its descent' being under the perfect control ofthe operator.

To enable those skilled in the art to fully understand and construct my invention,l will proceed to a more particular description ot' the same. Y

Figure l shows a perspective view of my invention, and Fig. 2 shows a side view of the same with the plate x removed.

G is the shaft to which the wheel E is permanently attached, which shaft also constitutes the drum W, having an ordinary spool attached to the same, upon which the rope holding the bucket may be wound.

G is the ratchet placed loosely upon said shaft G.

M is a friction band or clutch open at one side and having a projection on-either side Aof the said opening, as shown at 2 2, which projections fit into a recess in the ratchet-lever K, which recess is shown at 4t. On either side of the projections 2 2 is a lug or stop upon said friction-band, (marked O O,)which are in contact with the stops P P, as occasion may require.

K is the ratchetlevcr already mentioned, having at one end a number of cogs which admit of its being operated by the pinion S, attached to the -handle T, passing through a square opening, as shown at K, and fastened on the opposite side by a convenient nut, B'. At the other end of said ratchet-lever is a projection sufficient to hold the spiral spring.

D, which plays upon and the pressure Ot' which is regulated by the thumbscrew F, which has a collar, H, upon its inner side.

X is a metallic plate covering the entire surface of the windlass, or one side of the same, and is fastened by means of screws Y Y Y.

Front the description given it will be seen that by turning the crank in the direction indicated by the arrow l the wheel E moves easily within the friction-band M; but at any time the operator may choose, by a slight movement of the hand he can turn the pinion S either way, and cause the ratchet-leverK to so act as to bring the projections 2 2 nearer together, and thus diminish the size of the band, producing any amount of friction desired, thus retarding the descending bucket, o'r stopping it entirely. It will also be seen that by means of the thumbscrew F and the spring D, I can adjust the loose band or friction-clutch so that it will hold any required weight without producing' additional action upon the band M through the medium of the ratchet-lever K.

Having thus described my invention, whati claim as new, and desire to secure by Letters Patent, is

l. A hollpw crank having a ratchet wheel permanently attached thereto, as described.

2. The loose friction band or clutch having projections and stops,substantially as set forth, and operated by means of a ratchet-lever.

3. The ratchetlever, constructed as described, and operatedby means of the pinion S or its equivalent," and arranged with reference to the spring D'and thumb-screw F, as described.

GEORGEy RAGE.
